I'm a recent graduate and just completed my vacation work at one of the big Accounting firms. On Friday, they had a social/drinks which was really just to chat and network amongst the team. If you are sitting down and someone comes over to speak to you, should you remain seated or stand up, so you can be at the same eye level when they come speak to you. I'm wondering what will be good and respectful practices when this happens again
This answer comes from a western culture perspective.
If you are at a social event, and you are sitting by yourself, and somebody comes up to you to start a conversation, you should absolutely stand up, or offer them a seat so they may sit down.
It is a bit awkward for you to be speaking with them with your head at their crotch level.
If this is a social event, you should consider not sitting down to begin with. People are going to be moving about, ultimately you want to avoid the awkwardness to begin with.
